Rigid fixation and immobility of the implants has been recognized to have a significant impact on the peri-implant tissue response in immediate implant loading.
The rigid fixation reduces the mechanical stress exerted on each implant and prevents the risk of micromovements in relation to the surrounding zone.
The concept of intra-oral welding as a suitable technique for the fabrication of a restoration for edentulous case on the same day of surgery -> immediate loading.
